Explanation:

To determine the relationship between polyps and corals, we analyze each option:

• Option 1: Polyps are the individual organisms, and corals are colonies of polyps, not the other way around. So this is incorrect.
• Option 2: Corals are made up of many polyps (tiny organisms with hollow bodies), so this correctly describes their relationship.
• Option 3: Corals are not made up of "corals" as a component; they are made of polyps. So this is incorrect.
• Option 4: Polyps are animals (cnidarians), and corals are colonies of polyps, not algae. The symbiotic relationship is between polyps (corals) and algae (zooxanthellae), but polyps and corals themselves are not algae. So this is incorrect.

Answer:

B. Polyps and corals are both tiny creatures with hollow bodies (assuming the second option is labeled B; if the original options had labels, use the correct label with the text. Since the user's image shows the second option as "polyps and corals are both tiny creatures with hollow bodies", that's the correct one.)
